The St. Lawrence River Basin Study titled, "Watershed Protection of the St. Lawrence River Watershed with Special Consideration to Large Tracts of Land Part Two: The Salmon/Trout, Raquette, and Grasse Watersheds" is one of 10 EPA-funded State Wetlands Protection Program projects awarded to the Adirondack Park Agency, and marks the completion of detailed wetland and watershed maps for about 70% of the Park. Part I of this study focused on the St. Regis River Basin and was completed in 2000.
The St. Lawrence River Basin is ecologically unusual because of its concentration of large peatland complexes. Three-quarters of the land in the project area is wilderness, wild forest, or resource management, resulting in large contiguous forest areas.
The objectives of this study were to:
A total of 708 sub-watersheds were mapped in the 961,218.8 acres (388,993.0 ha) that comprise the Raquette, Grasse, and Salmon/Trout river basins. Out of this acreage, 122,711.3 acres (49,659.7 ha) were mapped as wetland, which constitutes 13% of the total watershed area. The influence of beaver activity was seen in 25% of the total number of wetlands, or 19% of the total wetland area.
Wetland maps and associated statistical data and habitat interpretations were provided to New York State Department of Environmental Conservation Unit Management Planners for inclusion into three UMPs: St. Regis Canoe Area, Bog River Complex, and Raquette Boreal Wild Forest.
Data collected in this project, when combined with the data layers from the Oswegatchie/Black and Upper Hudson watersheds, provides a consistent continuous picture of the wetlands and surface hydrology of these portions of the Park and will continue to be of immense value for wetland resource protection in the future.
This project was funded by a U.S. Environmental Protection Agency, Office of Wetlands Protection, State Development Grant No. CD992644, and was completed in cooperation with the Remote Sensing Lab at the State University of New York at Plattsburgh, and the New York State Adirondack Lakes Survey Corporation.
At the Remote Sensing Lab at SUNY Plattsburgh, thanks go to Kyriel Taylor, Michael Sundberg, Adrienne Pike, Lisa Walsh, Peter van Erp, Evan Kline, and Jaclyn Ammaturo. At the Adirondack Park Agency our gratitude is extended to the entire staff, especially Judy Smith, and Dan Fitts.
Although the research described in this report has been funded wholly or in part by the United States Environmental Protection Agency (EPA) under assistance agreement no. CD992644 to the New York State Adirondack Park Agency, it has not been subjected to the Environmental Protection Agency's peer and administrative review and therefore may not necessarily reflect the views of the EPA and no official endorsement should be inferred.
